MOUNTING FOR BONES.

T0 aZZ 1071 am it may concern lie it known that l, Bxnrmrrr J. PALMER, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful lmprowaui-ants in lvlountings :t'or Bones, of which the following is a specification.

This invention relates to an 1l!tlPl'()\'6IIltlllli in a mounting :t'or bones ot a body, and more particularly to a mounting of this character which may be used in the study of osteopathy and chiropractic.

The theory of chiropractic is that all dis cases are caused by displacen'lent of the vertebrte causing them to press upon the large nerve branches which pass out from the spinal cord orifices between the vertebrre, which pressure upon the nerve branches prevents (11C proper circulation ot the nerve :l'orces and thus causes the organs to which these ln-anches lead to become diseased, and the primary object of the present invention is the provision of a simple and etlicient mounting :t'or vertebral sections of such a character that the vertebral sections may be shifted relatively to each other so as to illustrate to the student, the results caused by such shitting or displacement of the vertebral sections.

Other objects of the invention will be apparent trom the detailed tilcscription hereina'ltcr, when read in connection with the aceompai'iying drawings forming a part hereot, wherein a convenient embodiment of the invention is illustratetl, and wherein like characters oil rejterei'ice refer to similar parts in the several views.

In the drawings: l igure 1 is a front elevation of the improved mounting. Fig. 2 is a plan view.

.leterring now more particularly to the drawings A A designate a pair oit supporting plates or members, the adjacent edges of which are slightly separated, and the end portions of whicl' are connected by parallel links l3 B, the ends of which are pivotally connected by suitable screws or other :lastening means 6 to the supporting plates A C C designate two superposed vertebral sections one of which rigidly secured to each ot' the supporting plates A A. In the particular embodiment of the invention illustrated in the drawings, each of the sections C C comprise one halt ot' a complete Specification of Letters Patent.

vertebra, such vertebra being cut vertically through the body and spinous process thereof to produce one of the sections 0. In securing the sections C C to the supporting members it A, each of said sections is secured with the flat side, produced in cutting the same, directly against the outer face of the supporting section, so that when the two sections have been secured to the supporting plates in their proper relation, :1 side view of the vertebrae is presented.

Interpostal between the adjacent ends of the bodies oi the sections U C is an intervertebral pad I)" which is conveniently formed o'l' t'elt, soft. rubber, or like material. lositioncd between the orifice formed between the transverse spinous prot es is a short piece of rubber or other elastic tubing l l which is int-ended to represent one of the nerve branches which pass out from the spinal cord through orifices in the vertebrae.

When the simporting members A A are in their normal or proper position, the sections C (l ot the vertebrae carried thereby will also be in their normal positions, and the tube E will not be compressed, Owing to the link C(HliltUliOIlS l:)etween the supporting niembcrs A. A. it will be seen that such members can be shifted laterally relatively to each other, and when the members are so shifted the vertebral sections will also be shifted relatively to each other and portions of the sections will be caused to engage the tube E and partially compress the same, thus vividly illustrating to the student the results which are prmluced by a displacen'icnt of one of the verleln'al sections relatively to the other. The displacen'ient ot the vertebral sections 0 C in this manner also shows the results of a disphurenwnt of one of the sections at the JOYtQlH'tI ot a. human body rel ativcly to the other upon the interverteln'al pad between the sections of the vertebrae.

The connection between the members A A is such that such members, when shifted relatively to each other, will remain in their shifted position until they are shifted relatively to each other to restore the same to their normal positions, so that ample op portunity is given to enable proper observation of the parts when in their normal positions.

\Vhile in the form of the invention illustrated in the accompanying drawings each of the sections C C is illustrated as comprising but one-halt ot a complete vertebra,

it is obvious that complete vertebralsections might, if desired, be mounted upon the sup porting members, and while but two sections of the vertebrae are illustrated in the accompanying drawings, it will be obvious that any number of sections or any. portion of a spine may be employed.

While a convenient embodiment of the invention is illustrated in the accompanying drawings, it will be understood that many changes may be made to the particular form and construction therein shown without departing from the spirit and scope of the invention as defined in the appended claims.

I claim 1. A mounting for bones of the character described comprising a pair of adjacent supporting members, a palr of superposed vertebral sections, one of which is rigidly secured to each of said supporting members, and means for connecting the supporting members whereby one of said members be moved laterally relatively to the other of said members.

2. A mounting for bones of the character described comprising a pair of supporting members, a pair of superposed vertebral sections, one of said sections being rigidly secured to each of said supporting members, pads between the adjacent bodies of said vertebral sections, and means for connecting the supporting members whereby one of said members may be moved laterally relatively to the other of said members.

3. A mounting for bones of the character described comprising a pair of supporting members, a pair of superposed vertebral sections, one of which is rigidly secured to each of said supporting members, an elastic tubular member positioned in the orifice formed between the vertebral sections, and connections between said supporting members whereby one of said supporting members may be moved laterally relatively to the other of said supporting members.

A. A mounting for bones of the character described comprising a pair of supporting members, a pair of superposed vertebral sections one of which is rigidly secured to each of said supporting members, a pad between the adjacent portions of the bodies of said vertebral sections, an elastic tubular member positioned in the orifice formed between the members may be moved laterally relatively, to the other of said members.

5. A mounting for bones of the character described comprising a pair of supporting members, a pair of superposed vertebral sections, one of which is rigidly secured to each of said supporting members, and a pair, of parallel links having their ends pivotally connected to said supporting members whereby one of said members may be moved laterally relatively to the other of said members. x

'6. A mounting for bones of the character described comprising a pair of supporting members, a pair of superposed vertebral sections, one of which is rigidly secured to each of said supporting members, a pad betweenthe adjacent portions of the bodies of said vertebral sections, and a pair of parallel links having their ends pivotally connected to said supporting members. I

7. A mounting for bones of the character described comprising a pair of supporting members, a pair of superposed vertebral sections, one of which is rigidly secured to each of said supporting members, an elastic tubular member positioned in the orifice between said vertebral sections, and a pair of parallel links having their ends pivotally connected to said supporting members.

8. A mounting for bones of the character described comprising a pair of supporting members, a pair of vertebral sections, one of which is rigidly secured to each of said sup porting members, a pad between the adjacent portions of the bodies of said vertebral sections, an elastic tubular member positioned in the orifice formed between the two vertebral sections, and a pair of parallel links having their ends pivotally connected to said supporting members.

In testimony whereof I afiix my signature in presence of two witnesses.
